Simcere Zaiming Pharmaceutical has achieved Investigational New Drug (IND) clearance from the FDA for SIM-0609, a novel CDH17-directed antibody-drug conjugate designed to treat advanced solid tumors. The IND approval follows a recent go-ahead in China and enables the commencement of clinical trials in the US.
